Sparda

Sparda (スパーダ) is a mighty demon who is known as the "Legendary Dark Knight" (伝説の魔剣士). Two thousand years ago, he "woke up to justice" and alone defeated Mundus and his legions. When sealing the netherworld, sensing his power had grown too strong, he intentionally sealed himself and his own demonic power in as well. Later, he escaped his prison and quietly reigned the human world and continued to preserve harmony. Before his death, he resurfaced in the modern day and married Eva, who gave birth to his twin sons, Dante and Vergil.

Description
In his human disguise, Sparda was a tall, handsome man with blue eyes, a young face, and slicked-back white hair. He is shown to have worn a purple Victorian outfit with a white cravat, a large red jewel around his neck, and a monocle over his left eye. While riding into battle on horseback, he would wear armor reminiscent of his demon form.

In his true form, Sparda was a slightly-larger-than-human-sized, vaguely insectoid demon with clawed hands, a scaly hide, a pair of downward facing ram horns, chiropteran wings with beetle-like wings underneath, hooves for feet, and reptilian spines protruding from his back. Parts of his body appeared to be made of grey scales with accents of red and purple. He also had gold veins on his hands and arms, chest, shoulders and back, a red diamond eye shaped gem in the center of his forehead, and skull-shaped gold knees and elbow guards with small horns. His most notable feature were his slit-like eyes, which glowed red and did not have pupils. He is often shown wreathed in fire, although it is uncertain if he was simply impervious to it or if he summoned it.

Personality
Although not much is known about him on a personal level, it is said that he was both rebellious like Dante and level-headed like Vergil. He was well revered and respected by many demons for his heroism while in service to Mundus, describing him as a 'hero among heroes'. Legends speak fondly of his courage, righteousness and his thankless missions to protect the human world at the expense of being labelled as a traitor by all of his demon brethren. Sparda's wife, Eva, always described him as being a noble fighter with courage and a righteous heart.

Sparda understood honor and possessed great wisdom. Sparda had two apprentices, Baul & Modeus, though he only entrusted his true strength and power to Modeus as opposed to his colder brother Baul. Not long before his rebellion, he swore an oath with his students to live true to their aspirations.

Before Devil May Cry 3 Manga
Sparda was once one of Mundus's loyal generals. During his time in service, he was the mentor of the twin brothers Baul & Modeus, and he entrusted his teachings to Modeus. At some point he saw the tyranny and injustice of his master and rebelled, fighting to save humanity. Before his rebellion, he made a pact with his students to live true to their aspirations and to carry them out. He alone defeated the hellish host, before moving on to the Emperor of Darkness himself. Sparda defeated Mundus, sealing him into a marble vault, and what was left of Mundus's armies retreated back into the demon world. In order to close the gateway, Sparda used his own blood, along with the blood of a human priestess, in conjunction with his sword and a mystical amulet. He poured his demonic energy into his beloved sword to close the door between realms, the Temen-ni-gru, though this also robbed him of the lion's share of his abilities. As an added measure, he also imprisoned within the tower its gatekeepers, Cerberus, Agni & Rudra, Nevan, Beowulf and Leviathan, and took the names of the Seven Sins in order to imprison them and set them as seals keeping the Temen-ni-gru underground. In Devil May Cry 4 it is revealed that he sealed another path to hell in Fortuna using the Yamato. Sparda's activities over the next two thousand years are shrouded in legend, though it is understood that for a time after defeating Mundus, he ruled over the humans before eventually vanishing. Sparda later appeared in the twentieth century where he met and fell in love with a human woman named Eva, who bore him twin sons.

Devil May Cry 3
Arkham uses the Sons of Sparda to open the gate to the Netherworld, in order to obtain the Force Edge and thus obtaining the powers of Sparda himself. While he is able to use it to temporarily take on Sparda's form, he is unable to truly resonate with it and soon transforms into a hideous mass of demonic ectoplasm.

Devil May Cry
Sparda is referenced frequently throughout the game. At the start of the battle with Mundus, Dante finally awakens the true powers of Sparda's sword, and assumes Sparda's form as a new Devil Trigger. In this form, Dante can fly, shoot fireballs from his fists, and summon a spectral dragon. While fighting on the ground during the second part of the boss battle, Dante can also charge the fireballs, and the range of his sword is greatly extended.

Devil May Cry: The Animated Series
It is revealed that Sparda once had two apprentices, the twin brothers Baul & Modeus. There is also a statue of Sparda in a park in the town where Dante lives.

Devil May Cry 4
The Order of the Sword is a group of demon hunters that worship Sparda. Nero, the main protagonist of Devil May Cry 4 is blood linked to Sparda, and referenced multiple times in Sparda's rebellious nature.

The demon Berial implies that he encountered Sparda when he came to the Human World two millennia prior, telling Nero, "You are just like he was..."

The readings of His Holiness reveal that Sparda is not just a devil: he has emotions and can love, and in this lies his strength. This actually explains why all of those who assert to gain his power fail, as not one of them did what they did because of love for humans.

Devil May Cry 2
During Dante's first meeting with Matier, the old woman reveals that Sparda once fought alongside the Vie de Marli clan. Dante mentions that Sparda once crossed into the Demon world and returned. It is also revealed that Sparda once fought against Argosax and Bolverk

Marvel vs. Capcom 3
Sparda is available as a downloadable costume for Dante, and his own Devil Form replaces Dante's while in Devil Trigger. He also makes a second appearance in Ultimate Marvel vs. Capcom 3 as the Devil Trigger form for Vergil's downloadable outfit, instead of Nelo Angelo as seen in the Special Edition of Devil May Cry 3.

Powers and Abilities
The exact extent of Sparda's powers remains unknown; but it is shown that his powers surpassed even the "Prince of Darkness" himself, evidenced when Sparda single-handedly defeated Mundus and his demonic armies, also implying that he possessed power upon a godly scale. Though it is to be seen that his powers stem from a heat related aspect indicating that he possesses a demonic form of pyrokinesis, the exact nature of his powers are uncertain as his true form appears to be partly corporeal-scales and flesh-and partly ghostly-as if made from smoke or shadow. As in Dante the abilities and utilization of fire and electricity seem to be among his abilities. Arkham himself likened obtaining Sparda's power to becoming a god. In Devil May Cry 3, Dante was unable to defeat Arkham, who wielded the Sparda sword (and thus Sparda's powers) at the time, until Vergil shows up. However, it should be noted that Griffon in the first Devil May Cry stated, after being defeated for the final time, that "[Dante's] are definitely the powers of Sparda. No, even more so.". Also, Nero was able to defeat Sanctus, who wielded Sparda and was connected to the powers of The Savior. It is suggested in Devil May Cry 4 that Sparda acquired the true extent of his power by embracing humanity, which would explain why the demons who attempt to augment their own power with Sparda's are unable to defeat the Sons of Sparda. He was also implied to be a powerful master swordsman, as he trained Baul and Modeus into powerful swordsmen and Modeus stated that Sparda was "the best swordsman in the Demon World", although Dante went so far as to mock his father's sword work when he faced Baul.

Weapons
Sparda is known to have used both Yamato and the Force Edge. The former he used as a key to lock the Demon World away from the Human World, and he sealed the power of the latter with the Perfect Amulet, turning it into the Force Edge. Also, in Devil May Cry 3: Dante's Awakening, it is stated that Rebellion is a memento from Sparda to Dante, though its exact significance is unknown.

He also used the Luce & Ombra, his own hand made pistols.

Trivia

 * In Devil May Cry and Devil May Cry 3, Dante can obtain the "Legendary Dark Knight" costume by clearing Hard mode. In Devil May Cry, this seems to actually be Sparda himself, as Dante's Ebony & Ivory are replaced with Sparda's Luce & Ombra. The sword Yamato is added to his arsenal, but players can still use Alastor. Yamato is basically a clone of Alastor, but when Sparda Devil Triggers, Yamato turns into the sword Sparda. Dante's DT and shadow are that of Sparda's devil form, no matter the equipped Devil Arm, though his abilities still depend on that Devil Arm.
 * In Devil May Cry 3, Dante's "DMC1 Dante" and "Coatless DMC1 Dante" costumes assume the form of Sparda while in Devil Trigger, possibly reference to how Dante, in the end of DMC1, takes the Force Edge and uses Sparda's Devil Form to defeat Mundus.
 * Sparda's coat and general dress being purple appears to be a combination of Vergil and Dante's trademark colors, or rather their red and blue being a split. His hair also seems to be a middle ground between Dante and Vergil, slicked back but not as spiky as Vergil's.
